2026 Volvo EC40 Twin: home charging cost in Arizona

In Arizona, home electricity runs 15.45¢/kWh — put a 2026 Volvo EC40 Twin's EPA-rated 34.8 kWh/100mi against that and 100 miles costs $5.38, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 66.4% less than gas per mile, here specifically.

What a year of driving costs

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2026 Volvo EC40 Twin charged at home in Arizona costs about $807/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,596 a year.

What one full charge costs

A 2026 Volvo EC40 Twin needs roughly 93.4 kWh to reach its EPA-rated 268-mile range, which runs about $14.43 at 15.45¢/kWh in Arizona.

How this compares nationally

This combination ranks 6,365 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Volvo EC40 Twin alone ranks 144 of 400 models for efficiency; Arizona alone ranks 25 of 51 states for electricity price.

Before you install a home charger in Arizona

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
